Abstract

A heating module for recreational vehicles (RVs), including a heat exchanger, a heating water inlet, a heating water outlet and a cold water inlet. The heat exchanger is communicated with the heating water inlet. A side of the heat exchanger is provided with a fan to generate air flow, so as to carry the heat generated by the heat exchanger to an interior of the RV. The heating water inlet is communicated with a water outlet of a water heater. The heating water outlet is connected with the heat exchanger, and a water pump is provided on a pipeline between the heating water outlet and the heat exchanger. The cold water inlet is configured to be connected with tap water or a water storage tank of the RV. A water flow sensor is provided on the cold water inlet.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A heating module for recreational vehicles (RVs), comprising:
 a heat exchanger;   a heating water inlet;   a heating water outlet; and   a cold water inlet;   wherein the heat exchanger is communicated with the heating water inlet; a side of the heat exchanger is provided with a fan; the fan is configured to generate an air flow to carry heat generated by the heat exchanger to an interior of an RV; and the heating water inlet is communicated with a water outlet of a vehicle-mounted water heater;   the heating water outlet is connected with the heat exchanger, and a water pump is provided on a pipeline between the heating water outlet and the heat exchanger; and   the cold water inlet is configured to be connected with tap water or a water storage tank of the RV; and a water flow sensor is provided on the cold water inlet.   
     
     
         2 . The heating module of  claim 1 , further comprising:
 a controller;   wherein the controller is electrically connected with the fan and the water pump; and the controller is also electrically connected with a temperature sensor in the RV.   
     
     
         3 . The heating module of  claim 1 , wherein a check valve is arranged on the heating water outlet. 
     
     
         4 . The heating module of  claim 1 , wherein a check valve is arranged on the cold water inlet.
